'To all whom it may concern ALFRED A. HOLLOMAN, F DALLAS, TEXAS.

BLOW-OUT GUARD.

Be it known that I, ALFRED A. HoLLoMAN, citizen of the United States, residing at Dal- Il las, in the county of Dallas and State of 1 Texas, have invented certain new and useful Improvements in Blow-Out Guards, `of which the following is a specification.

My invention relates to a new and useful blow-out guard for double tube tires, and its object is to provide a split sleeve of suitable material which may be inter osed between the inner and outer tubes o a pneumatic tire, to reinforce an apertured or weakened place in the outer tube or casing, preventing the innertube from blowing out at such a point.

It isa further object of the invention to provide a blow out guard thatJ may be very quickly applied to the tire without'tlie use of special tools or mechanical skill, and which will securely remain in its proper place in the tire until manually removed.

Finally the object of the invention is to provide a device of the character described, that will be strong, durable, simple and eilicient and comparatively easy to construct.

With these and various other objects in view, my invention has relation to certain novel features of the construction and use, an example of which is described in the following specification, and is illustrated in the accompanying drawing, wherein:

Figure l is a. view showing in side eleva tio-n the application of my blow out guard to a double tubed tire, the outer tube or casing being partially broken away to more clearly illustrate the blow out guard. p Fig. 2 is a view showing in side elevation the blow out guard alone. Fig. 3 is a transverse sectional view, taken upon the line w-m of Fig. 1. *l

Referringnow more particularly to the drawing, vwherein like reference characters designate similar parts in all the figures, the numerals l and 2 respectively denote the outer and inner casings of an ordinary double tube tire, and 3 denotes a split sleeve, the longitudinal edges of which are slightly spaced when said sleeve is made to embrace the casing 2. The material composing the sleeve 8 will preferably be a combination of canvas'and rubber such as will give great strength without permitting the passage of air. `Within the sleeve, there issecured to one of the longitudinal edges thereof a tongue ll, which when the sleeve is inter- Specication of Letters Patent.

posed between the inner and outer casings of a. tire extends across the gap between the adjacent longitudinal edges of the sleeve 3, counteracting the tendency of the innerkcasing to bulge through said gap due to air pressure. It is preferred to thicken the central portion of the tongue 4 as indicated at eta, since said central portion is exposed to the greatest pressure by the inflated inner tube. The tongue 4 may be formed of similar material to that composing the sleeve 3.

Adjacent to one of the longitudinal edges of the sleeve 3 there is exteriorly secured a strip 5 of flexible material, preferably leather, a row of stitching 5a being preferably employed to secure said strip to the sleeve 3. The strip 5 projects slightly beyond the adjacent edge of the sleeve 3, and is formed with a plurality of equidistant loops 6. j To the other longitudinal edge of the sleeve there is exteriorly secured a ,strip 7 of flexible material, preferably leather, and secured to the sleeve 3 preferably by a row of stitching 71. In the strip 7 there are provided a plurality of slots 8, through which the loops 6 may be respectively passed as is clearly shown in Fig. l of the drawing.

To one extremity of the strip 7 there is riveted or otherwise secured a thong 9,which after the loops 6 have been projected through the slots 8 will be passed through all of said loops, thus positively preventing the withdrawal of the loops from the slots, and holding the inner casing firmly embraced within the sleeve 3 when said casing is inflated.

By the use of the above described device a. weakened outer casing may be so reinforced that its period of usefulness will be very much increased. The device can fui'- ther be used to great advantage to temporarily repair a tire subsequent to a blow out, the inner tube being patched in this case at the point where it has given away, and my low out guard being employed to protect the patch until the outer casing can be vulcanized at the weakened point.

The invention is presented as including all such modifications and changes as propiio vided integrally with said folded member,4

seli` and cut out along the fold whereby' e plurality of spaced marginal loops are prosaid folded member being secured to the eX- terior face of one of the longitudinal edges of said sleeve, a flexible strip secured to the opposite longitudinal edge of the sleeve, and rovided with elongated slots having tlieir ongtudinal axes parallel to the longitudinel edge of the sleeve, each slot receiving one of the loops of the folded member and a flat Chong secured at one of its ends to one end of the lest named strip and laced through the loops of the folded member.

2..ln a blow out guard for pneumatic tires, a flexible air proof sleeve split longitudinally, e flexible member folded upon itself and cut out along the fold whereby a plurality of spaced flat marginal loops are provided integrally with said folded member, said folded .member being secured to the exterior fece of one of the longitudinal edges of seid sleeve, e liexible strip secured iat-@airway be obtained for tive cents each,

miniem to the opposite longitudinal edge or" the sleeve, and provided with elongated slots having their longitudinal axes parallel to the longitudinal edge o' the sleeve, each slot receiving one of the loops of the folded member, a flat thong secured at one of its ends to one end of the last named strip end laced through the loops of the folded .member, and a third strip oi flexible material secured to the inner face orn one ofi the longitudinal edges of the sleeve and bridging the gap between the longitudinal edges of the sleeve, the thickness of seid third strip being increased between the longitudinal edges of the sleeve.

In testimony vvliereor1 l have signed my name to Athis specification in tbe presence of tno subscribing Witnesses.
